Raymond Chen's The Old New Thing - one of the best Windows blogs on the web - has a very interesting item up about a certain bit of behaviour in Windows 95 I was unaware of. Basically, there's a neat little trick where you can close and move the Start button. It wasn't a feature, but a bug.

Many, many moons ago, I used to work at a CompUSA and one of the more amusing pranks I learned was taking a screen shot of the desktop, setting it as the back ground, deleting the icons and finally hiding the start menu. For such a simple trick, I've had great success with it. Especially on the demo machines at said CompUSA.
